The OS X equivalent of an iOS passcode is FileVault. Its current incarnation (v2) uses full disk encryption and doesn't have a (known) backdoor. (v1 used per-user encryption but didn't protect the rest of the disk, and v3 might use AFS to encrypt the whole disk in a way that users can only decrypt their own data and shared areas of the filesystem, not other users' data.)
Firmware passwords are more like Activation Lock for iOS. They make it harder to reuse a stolen computer and stop some less-invasive tampering, but don't offer any guarantees about protecting your data.
